TANK OR CAN.

Specification of LettersPatent.

Patented April 3, 1906.

Application filed June 3, 1905. Serial No. 263,519.

.States, and residents of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements in Tanksor Cans, of which the tollowing is a specification;

Our invention relates to the construction of the bottoms and chimes ofmetal tanks, cans, &c., and is an improvement upon Let ters Patent N 0.755,971, granted to us March 29, 1904.

In the accompanying drawing, to which reference is made, and which formsa part of this specification, the figure is a sectional elevation of ametal tank or can having our invention applied thereto.

In the drawing, 2 designates the body of the tank or can, and 3designates the bottom of the can, which is formed integral With theinner flange 4 and outer flange 5, the lowermost point of the outerflange 5 being on a level with the fold or. bend 6 in the bottom 3. Theflanges at and 5 are spaced from each other, and in the bottom of thespace is fitted a metal ring 7. The bottom of the body 2 is placed inthe space between the flanges, so as to rest upon the ring 7, and thenthe whole is placed upon a level table or support and the parts brazedor soldered together from the top of the outside flange 5, forming twothicknesses of 8.10 of brazing metal or solder. In the work of brazingor soldering the outer flange forms a head or dam for the molten metal,so that as soon as the molten metal rises on the inside to a level withthe angle 6 it will overflow the outside flange 5,

and thus apprise the workman that the soldering is perfect and complete.Small indentations 12 may be formed in the ring 7 to allow free flow ofthe molten metal,or notches may be formed in the lower edge of the body2. The molten metal not only secures the flanges 4 5 to the body of thecan, but incases the ring 7, and the ring being of steel or other rigidmetal and of greater thickness than the thickness of the metal com osingthe body of the tank or can braces the flanges 4 and 5 and also protectsthe bottom edge of the body, thus forming a very strong and durablestructure.

Having thus described our invention, what we claim, and desire to secureby Letters Patent is 1 A metal tank or can comprising a main body, abottom having an inner and outer flange a ring ofgreater thickness thanthe thickness of the material composing the body of the can placed inthe bottom of the space between the flanges forming a base to andsupporting the lower edge of the body and brazing metal or solderinterposed between the main body of the can and the said flanges,substantially as described.

2. A metal tank or-can comprising a main body, a bottom having an innerand outer flange, a ring formed with notches placed. in the bottom ofthe space between the said flanges and brazing metal or solderinterposed between the main body of the can and the said flanges,substantially as described.
